CULTIVATOR.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed March 9, 1914. Serial No. k823,348e

T0 all whom it may concern: Y

Be it known that l, CHARLES Srnnssnn, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles, State ofCalifornia, have invented new and useful Improvements in Cultivators, ofwhich the following is a specification.

It is the object of this invention to proV vide a cultivator adapted tocultivate ground where the latter has been previously formed into hillswithout destroying the hills, or changing the inclination of the sidesof the furrows by automatically adjusting itself to sloping sides ofvarious inclinations. l

lt is also an object to provide a cultivator with a plurality ofsub-soilers which pre-4 cede the cultivator teeth and break up portionsof the soil which may not have previously been turned over.

It is a further object to provide a cultivator with a plurality ofshoes, one acting as a runner to hold it straight, and others adapted tosupport the cultivator when it is being transferred from one place toanother without disturbing the soil.

The invention is illustrated in the accompanving drawing, in which:

Figure 1 is a side elevation of the cultivator. Fig. 2 is a plan viewthereof. Fig. 3 is a rear view showing the inclined arrangement of theteeth of the cultivator to accommodate the mounds, and illustrating themanner in which the cultivator will follow the previously formedinclination of the surface between the mounds.

More specifically in the drawings, 5 designates the ground which hasbeen previously cultivated and formed into mounds 6 for the cultivationof certain classes of agricultural products, corn being usually grown onsoil thus mounded.

The cultivator consists mainly of a V- shaped frame, having side members7 and 7 hingedly connected together at their point of intersection bymeans of a hinge S. The side frames are preferably formed of angle ironand bent to the configuration shown, transversely of which members aresecureda plurality of cross bars designated 9, 10, 11, and diagonalbrace bars 12, those numbered 9, 10, and 11 being hinged at 13 at theircenters in alinement with the hinge S so that they may be bent to theangular formation shown, corresponding with the angle of the ground line'intermediate the rows of the growing crop, and which angle can bevaried by manually adjusting the side frames 7 and 7 in relation to eachother. T he forward end of each side frame 7 and 7 is provided with aclevishook which is formed on the end of an angular standard 14, whichis secured to thc frame members by means of the bolts 15. A bracket 16on the forward ends of the frame members extends beneath the lower edgeof the frame members and forms a forward support for a pair oflongitudinal shoes or runners 17-17, which are preferably formed of Hatmetal strips bent at their forward ends ahead of the frames 7 and 7 toform supports 18 for the double divided shovel 19 or plow shoe.

rl`he rearwardly extending portions of the runners 17 and 17 are carriedin a plane corresponding to the ground level, and the frame members 7and 7 are inclined in relation thereto, and are bent upward ahead of thebrace 9. The rear portions of the runners are extended parallel withtheir' lower portion and secured to the most dependent portion of eachof the braces 9, 10 and 11 on opposite sides of the hinges 13 bysuitable rivets or other fastenings.

Mounted slightly to the rear of the draw bar 1% on each of the framemembers 7 and 7 are shoes 20 bent to the configuration shown, so thattheir outer faces project beyond the sides of the frame members 7 and 7in such manner that when the frame is tipped upon its side to betransported from one point to another, it will ride upon one of theshoes and upon a shoe 21 formed on the rear ends of the frame members 7and 7.

The bar 9 is provided with a plurality of plow shoes or sub-soilers 22,one of which is placed on each side of the center line of theinstrument, these sub-soilers having the usual threaded extensions whichare disposed through bores in the base 9 and either bolted or rivetedthereto. The cross-bars 10 and 11 support plain harrow teeth 23 of theusual square cross section pointed in the ordinary manner and secured byany well known means in vertical position to the cross bars; teeth 23being also mounted on the bar 9 on opposite sides of the sub-soilers 22.

To facilitate lifting and turning the cultivator suitable handles 24:are provided, which are shown bridging the two crossbars 10 and ll andsecured thereto by means of rivets 25; these handles extending upwardlyand rearwardly convenient to the reach of the operator.

As a means for preventing,` the leaf meinbers of the cultivator fromtolding,` together when turning corners and when tra nsporting it fromone place to another on the side runners 2O and 2l, upwardly andinwardly curved bars are mounted on the cross bar l0 With their adjacentends spaced such d istance apart as to ierinit oit sutlicient movementthe side portions of the cultivator relation to each other to lforni thedesired furrow, and which members on abutting against each other Willact to prevent the side portions of the 'frame from folding together.

A, short chain 127 loosely connects the ends of the members 2G andserves to prevent the side members of the frame 'from doubling in theopposite direction. This chain 27 is connected to hooks 28 in the endsof the members 26 and can be adjusted thereon so as to limit the extentof horizontal straighteniiig,` ot.' the side members of the frame inrelation to each other, as desired.

ylhe operation of the cultivator Will be readily understood; the doubleshovel 19 breaking up small portions of uncultivated soil which may havebeen lett in the center of the rovvs, the drag` trame formed by thetraine members 7 and Y sinooths the soil and builds up the mounds, therunner 17 guiding` the cultivator in the Yurrovv, the ploiv shares 22cultivate where a strip of uncultivated soil may iave been left, and theteeth A3 pulverising the soil to the proper degree, so that a inostettlcient and convenient combination cul"ivator is provided.

By raising or depressing` either of the handles 24k the leail portionsof the cultivator on opposite sides of thehinges 8 and 13 may be movedinto any desired inclination in relation to the opposite leaf portion.

What l claim is:

l i.. an angularly formed frame, the sides t'iere of extending,`upwardly and outwardly, a plurality of cross bars supported thereon, alongitudinal runner eattending` from end to end thereof, and a pluralityof cultivating devices of ditl'erent 'types supported on said runnersand said cross bars.

2. A combination cultivator, comprising an angularly formed frame, thesides eX- tending upwardly and outwardly from their junction, aplurality of cross bars transversely supported thereon, certain of saidcross bars being formed with dependent teeth supporting sections, harroWteeth supported thereon at an angle to said sections and parallel witheach other in a vertical position, and a plurality ot runners secured tosaid trame adapted to support said cultivator in operative andinoperative positions. Y

3. i combination cultivator, comprising,` angularly disposed iframemembers hinged a: their point of intersection, a series of cross barsconnecting the outer ends of the side trames hinged at their centers, arunner connected. at its forward end to the side trames, and at itsrearward end to the cross bars, a shovel mounted at the apex of the sideframes, and cultivating devices depending;` from said cross bars.

d. A cultivator, comprising` an angular frame hinged at its center toform leaf inein- -bers adapted to be rocked independent of each other, ashovel at the apex oi the traine, anl depending,` cultivating devicescarried on the rear portion o' the traine.

f. i cultivator, comp ising an angular traine hinged at its center toform leaf meinbers adapted to be rocked independent ot each other, ashovel at the apex of the trame, depending cultivating devices carriedon the rear portion of the frame, and a runner e2;- tending` centrallyof the frame and disposed in aguilar relation thereto.

6. fr cultivator, comprising` an angular traine hinged at its center toform leal" nien bers adapted to be rocked independent oit each other, ashovel the apex or the frame, depending cultivating devices carried onthe rear portion oi" the traine, a runner eXtendy ing centrally of theframe and disposed in angular relation thereto, and means for liraitingthe movement of the leaf members of the 'frame in either direction inrelation to each other.
